The Franklin
Institute Science Museum "Ben would have been proud to see this site.
It's a guide to the Philadelphia museum that bears his name as well as
a virtual version that provides exhibits on science, the heart and, of
course, Ben Franklin. Check out the rocket launch video or have museum
staffers answer your science questions online." [Excite

The Field Museum
of Natural History "Kids will love the exhibits on dinosaurs and other
kiddie friendly fossils at this wonderful Chicago museum. Artists will
want to see the Javanese masks. There is also a teacher's page and pictures
and information on up and coming exhibitions for everyone. This site's
a keeper." [Excite Reviews]

The ability to see Earth from space has forever changed our view of our
global home. We are now able to look at this planet as a whole, with its
atmosphere, oceans, lands masses, and other interacting global systems.

Crossroads
of Continents combines modern research in North Pacific (Northeastern
Siberia and Alaska) anthropology and archeology with the presentation of
many important objects from early collections. This exhibition attempts
to capture the wide diversity of North Pacific cultures as well as their
historical development from the end of the last Ice Age to the modern day.
Human populations began moving into Northeastern Siberia over 16,000 years
ago from the more temperate regions of eastern Asia, spreading north and
east with the passing of the last Ice Age until they crossed into the Americas
via Alaska. That great migration was only the beginning of the story...

Basic arithmetic might be best learned with an abacus.
Children who learn with one have a better intuitive understanding of numbers
and their relationships, and often become quite adept at rapid mental arithmetic
with large numbers. Children should have a physical (real) abacus, but
here's an on-line model you can use to get used to the idea.

"The theme of this book is that a universe comes into
being when a space is severed or taken apart. The skin of a living organism
cuts off an outside from an inside. So does the circumference of a circle
in a plane. By tracing the way we represent such a severance, we can begin
to reconstruct, with an accuracy and coverage that appear almost uncanny,
the basic forms underlying linguistic, mathematical, physical, and biological
science, and can begin to see how the familiar laws of our own experience
follow inexorably from the original act of severance."

These are two good presentations
of the Laws of Form material, with links to other relevant
Web pages.

"The Substance of a Non-Numerical
Arithmetic is the intellectual concept of the "Existence of Objects", whether
the Objects are real or imagined. Needless to say, any such discussion
of existential import ultimately has a spiritual genesis."

Kali.
"You can use Kali to draw Escher-like tilings, infinite knots, and other
cool stuff. It lets you draw patterns in all of the 17 planar symmetry
groups." Kali is one of ten programs offered at the

The gravitational pull of a suspected super-massive black
hole forms a frisbee-like disk of cool gas, at the core of an energetic
galaxy. Subsequent Hubble observations of yet another active galaxy (M87)
confirmed the reality of monstrous black holes -- gravitational ``sink
holes'' that trap everything, even light. November 1992. Click
